Excitatory Mode vs Normal Mode
Pictured waveforms were generated by the FB128 and plotted in Synapse with the following
settings:
Wave Filter Settings:
High Pass: 300 Hz, Low Pass: 5000 Hz
LFPx Filter Settings:
High Pass: 0 Hz, Low Pass: 300 Hz
Channel Mapping Mode
Starting with serial number 2000, the FB128 includes a diagnostic mode that presents a unique
waveform on every channel. This is useful for mapping channels or for detecting shorts on the
headstage.
Press and hold the MODE button on the FB128 until the LED starts
fl
ashing, which indicates the
FB128 is in channel mapping mode. Each channel plays a frequency encoded waveform that
creates a unique binary pattern that can be mapped to channel number. See the image below.

fl
y press the MODE button again to cycle through the available channel count options until
it matches the headstage you are testing.
